We used archival Spitzer Space Telescope mid-infrared data to search for young stellar objects (YSOs) in the immediate vicinity of two bright-rimmed clouds, BRC 27 (part of CMa R1) and BRC 34 (part of the IC 1396 complex). These regions both appear to be actively forming young stars, perhaps triggered by the proximate OB stars. In BRC 27, we find clear infrared excesses around 22 of the 26 YSOs or YSO candidates identified in the literature, and identify 16 new YSO candidates that appear to have IR excesses. In BRC 34, the one literature-identified YSO has an IR excess, and we suggest 13 new YSO candidates in this region, including a new Class I object. Considering the entire ensemble, both BRCs are likely of comparable ages, within the uncertainties of small number statistics and without spectroscopy to confirm or refute the YSO candidates. Similarly, no clear conclusions can yet be drawn about any possible age gradients that may be present across the BRCs. © 2013. The American Astronomical Society. All rights reserved.

While carefully plotted lesson plans are invaluable in a classroom, tuning into the flow of the moment is just as essential. My experience has shown me that the most effective teaching happens when everyone in the room is in synch with one another. Teaching requires intuiting what each student is experiencing individually and adjusting in order to bring the room to a united rhythm. Too often we define teaching in terms of curriculum, assessment, and practical measures that do not encompass this instinctive evolutionary skill. Teaching is a natural cognitive ability that requires human interaction and is optimal when a form of synchrony or flow exists in interactions. As an experienced classroom teacher, I describe how these principles infuse my practice, which I hope serves as a useful lens for the Mind, Brain, and Education (MBE) research community in its quest to uncover the underlying processes of teaching. © 2013 The Authors.

Recently, Lattelais et al. have interpreted aggregated observations of molecular isomers to suggest that there exists a "minimum energy principle," such that molecular formation will favor more stable molecular isomers for thermodynamic reasons. To test the predictive power of this principle, we have fully characterized the spectra of the three isomers of C3H2O toward the well-known molecular region Sgr B2(N). Evidence for the detection of the isomers cyclopropenone (c-C3H2O) and propynal (HCCCHO) is presented, along with evidence for the non-detection of the lowest zero-point energy isomer, propadienone (CH2CCO). We interpret these observations as evidence that chemical formation pathways, which may be under kinetic control, have a more pronounced effect on final isomer abundances than thermodynamic effects such as the minimum energy principle. © 2015.

In this paper, we report findings from an exploratory study of player and team performance in Halo 3, a popular First- Person-Shooter game developed by Bungie. In the study, we first analyze player and team statistics obtained from the 2008 and 2009 seasons for professional Halo 3 games in order to investigate the impact of change in team composition on player and team performance. We then examine the impact of past performance on future performance of players and teams. Performing a largescale experiment on a real-world dataset, we observe that player and team performance can be predicted with fairly high accuracy and that information about change in team composition can further improve the prediction results. © 2011 IEEE.

Antimicrobial peptides are a promising alternative to traditional antibiotics, but their utility is limited by high production costs and poor bioavailability profiles. Bacterial production and delivery of antimicrobial peptides (AMPs) directly at the site of infection may offer a path for effective therapeutic application. In this study, we have developed a vector that can be used for the production and secretion of seven antimicrobial peptides from both Escherichia coli MC1061 F’ and probiotic E. coli Nissle 1917. The vector pMPES (Modular Peptide Expression System) employs the Microcin V (MccV) secretion system and a powerful synthetic promoter to drive AMP production. Herein, we demonstrate the capacity of pMPES to produce inhibitory levels of MccV, Microcin L (MccL), Microcin N (McnN), Enterocin A (EntA), Enterocin P (EntP), Hiracin JM79 (HirJM79) and Enterocin B (EntB). To our knowledge, this is the first demonstration of such a broadly-applicable secretion system for AMP production. This type of modular expression system could expedite the development of sorely needed antimicrobial technologies. © 2016 by the authors; licensee MDPI, Basel, Switzerland.

The market for video games has skyrocketed over the past decade. In the United States alone, the video game industry in 2009 generated almost US$20 billion in sales. Furthermore, according to Lenhart et al. (2008), an estimated 97% of the teenage population and 53% of the adult population are regular game players. © 2006 IEEE.
